Application filed Gctober 19, 1914-.

T0 @ZZ whom it may concern y Be it known that I, I'IARRY E. FossEN- kunnen, a citizenof the United States, re siding in the city of Richmond, in the county of Wayne and State of Indiana, have invented a new and useful Chase-Lock Bar for Printing-Presses, of which the following is a full, clear, and comprehensive eX- position and specification, being such as will enable others familiar with theart to which it pertains to make and use the same with exactitude.

My invention relatesto improvements in printing presses, particularly those having a horizontal bed adapted to move forward and backward carrying a chase of types, and with a cylinder adapted to revolve above the bed and in contact vwith the bearers or tracks carried bythe edgesof the bed.V

This invention relates, more particularly, tol the means for securing a chase of types in operative position upon the surface of the bed. o

In securing a chase of types on the bedplate of a press it is customary to fill in the spaces around the chase with furniture, or blocks, and thenclamp the chase in place, but this plan is very unsatisfactory, as the blocks are' liable to buckle thereby freeing the chase, and also when the chase is small it requires a great number 'of blocks. of furniture to fill in the spaces.

My rinvention comprises a single space bar which is adjustable at convenient points forward and backward within the limits of the face of the bed, whereby the 'working extent of the face of the bed may be varied according to the size of the chase which it is desired to secure, thereby minimizing the amount of furniture required and also making the chase more secure.

The object of my invention, broadly speaking, is to provide means for locking a chase of types upon the surface of a bed of a printing press, the said means being strong and durable in construction, positive in action, neat and mechanical in appearance, easily operated and controlled, and which Vcan be manufactured and sold at a comparatively low price.

More .specifically stated my object is to provide a chase-lock bar for printing presses, the same being adapted 'to be adjustably secured at any desired point along the length of the bed, and to be detachably Specication of `Letters Patent.

side of the bed, whereby the workingsurface of the bed maybe varied in size to Y accommodate the chase to be secured, there? by dispensing with most of the furniture Y usually `employed in locking the chase in position, also accurately squaring the chase with relation to thebed, making the chase more secure in its operative position, and minimizing the labor required to secure the chasein position on thebed.

Other minor objects and particular advantages of my invention will be made ap? parent to the `expert in the course of the following description, andthat which is new will be correlated in the appended y claims. Y

rllhe preferred means for carrying out the principles of my invention in a practical manner is shown in the accompanying drawings, in which Figure l is a front perspective view of a portion of a printing press, showing my invention in connection therewith in operative position, only such portions of the printing press being shown as is necessary for a clear understandingofthe application of my invention thereto. Fig. 2 is a plan view of one end portion of the space-banias itwould appear in locking or operative position.

Fig. 3 is a plan'view of the other end por- Ainner or opposing face view of one of the bearers.

Similar indices denote ,like parts throughout the several views. v

Inforder that the construction, the operation, and the application of my invention to a printing press, may be fully understood and' appreciateol `I will now take up a detailed description thereof in which. I will set forth the invention as briefly and as comprehensively as I may.

In the drawings letter A denotes the horizontal bed-plate, which is a part of or is carried bv the usual body B. The bed-plat`e is adapted to slide forward and backward vinV the frame H ofthe press, which latter rests upon the floor. Mounted in the frame `H of the machine is the revoluble cylinder C, which is located above the bed-plate but is not in contact therewith.

Securedon the surface of the bedeplate and rising from thel edges thereof are the bearers D and E; and carried by the ends lof the cylinder are the rollersV F and G which are adapted to revolve on the surfacesl of the bearers as the bed-plate moves forward and backward. Attached to the front edge of the-bed-plate are a plurality of clamps, as thelclamps I and J', which are adapted. to bemoved forward and backward by therespective screwsK and L.

ALetter Mdenotes the chase, which is simi ply a mtal frame adapted' to lie flat on the surface of the bedfplate. p 1^ Letter N denotes the form, or a column of types, fromwhich the printing is made. The form maybe'locked vin the chase M as follows: Locatedaround the inside Vof the chase are the furniture blockse, b, @and ai.' Vandv placed around the form N are the furniture blocks e, Vf, 'g and Located be` n tween the furniture) blocks a and c is'the quoin O; 'between the furniture blocks and 7 l'is"the`xquoin` P; between thev furniture blocks c and gis the quoin Q; and between"V the furniture blocks d and 71, is the quoin'R.

Y'The said vopioins being for the purpose of wedging and locking the form in the chase.

y Letters T andU denote the outerfurnitureblocks, that kis the furniture blocks out- Vside ofthe chase containing the form.

' Allfofthe rparts above mentioned are of ordinary. design and they may be variously changed as desired, as my invention is not to be rvlimited Yto the particular construction above mentioned. I'

Myl invention proper comprises a flat metal barl1, whoselength is such as to "allow it to fit `'snugly between the two bearers Dand E, asin Fig. 1.

Formed into each end of the bar 1'are Vtwo cylindrical apertures, or cavities, as the vthe plungers outward to theirlimits.

l Formed in the upper face ofthe barl, over-each of the apertures 2, and extending down into, and out through the edge of, the

A,bar even with the lower line of said apertures, are the U-shaped notches 11, 12, 13

Thetwo side portions of each of the said notches are at right angles to their plunger, and open out through the edges of the bar, while thethird or body portion of each notch is parallel with the plunger.

Rigidly secured to the central portion of each plunger 3, e, 5 and (i, is a stem, as the respective stems 15, 16, 17 and 18. The said stems afford means for manually moving said plungers, and also providing means for locking the plungers in either operative or in inoperative position, and they are adapt-y ed to be moved in a vertical position in the body portion and to be 'turned down hori-y zontally in either of the side portions of the respective notches,`to secure the plunger in its projected positionl as in Fig. 2; or in in# operative position yas in Fig. 3. The free end portions of said stems project out slightly beyond the edges of the bar as shown, to afford means whereby they may be engaged by ones hand, or by a tool, for turningv them up into vertical position, that is to the position shown in Fig. 5.

Formed in the inner or opposing faces of the bearers D and E are 'socket apertures 19 and 20, respectively. The said socketiapertures are adapted to receive therein the pro- 'jected portion of the plungers when the plungers are brought into rline therewith.

.Zlodus operandi: In practice the operation of myinvention is very simple,-The furniture block T is firstplaced on lthe bedplate and in contactr with the faces of the clamps I and J. The chase,`in which the form has been previously locked, is then placed onthe bed-plate with itsforward edge in contact with tlie furniture block T. The', furnitnre block U. is then placed in contact with the rear edge of the chase. The neXtoperation is to bring my invention into action. This is done bybringing the bar 1 to the rear of the furniture blockU andl with its endsin contact with the opposing faces ofthe bearers D and E, but priortheretoall of the plungers should have been drawn back andvsecured in inoperative position as in Fig. 3. The bar 1 is then slid forward on the bed-plate and against or near the furniture block U and in such position that all of the plungers will each be in alinementwith one ofthe sockets 19 and 20. After the bar is thus located then all of the stems 15,v 16, 17 and 1S are then turned up in vertical position, Vas in Fig. 5, which will permit the plungers` to be forced.V into theirk respective socketsy 19 and 20 by their respective springs. The stems, above referred to, should then be turned down horizontally, `as in Fig. 2,

which willl lock the plungers in operative' position, and thereby retain the bar'in its proper place. vIt is now evident that the bar 1 will be securely locked in its `adjusted po-v sition between the bearers D ,and E, then byV simply tightening the screws K andL theV` said parts wilt pressed against the bar 1\ where they will be securely locked in operative position on the bed-plate ready for the operation of printing in the usual manner.

I desire that it be understood that various changes may be made in the details of construction, from that herein shown and described, without departing from the spirit of my invention and without sacrificing any of the advantages thereof.

Having now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, is-
